GAGE-GLASS FOR STE AM-BOILERS.

Specification of Letters Patent.

Patented June 22, 1909.

Application filed November 30, 1908. Serial No. 465,280.

To all whom it may concern:

Be it known that I, Oscar: OTTESEN, a subject of the King of Denmark,residing at Tacoma, in the county of Pierce and State of ashington, haveinvented certain new and useful Improvements in Gage-Glasses forSteam-Boilers, of which the following is a specification.

This invention relates to gage-glasses for steam boilers, which are usedto indicate the stage of water and steam in the boiler.

The invention has for its object to provide a multiple gage-glass ofsimple and improved construction whereby, in the event of breakage of orinjury to one of the glass tubes constituting the units of the device,the flow of water and steam may be directed into another tube, thusenabling the water stage to be continuously observed without stoppingfor repairs and enabling repairs to be postponed to a future convenienttime.

Further objects of the invention are to simplify and improve theconstruction and operation of this class of devices.

Vith these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention; it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention may be resorted to when desired.

In the drawingsFigure 1 is a front elevation showing the improved gageglass in position for operation. Fig. 2 is a side elevation of the same.Fig. 3 is a vertical sectional View taken on the plane indicated by theline 33 in Fig. 1. Fig. 4 is a vertical transverse sectional view takenon the plane indicated by the line 41-4: in Fig. 2. Fig. 5 is ahorizontal sectional view taken on the plane indicated by the line inFig. 1. Fig. 6 is a perspective view of the regulating valve. Fig. 7 isa perspective detail view of the try-cock.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The frame of the improved gage is composed of casings 5 and 6, havingtubular extensions 7, which are exteriorly screwthreaded, as shown at S.to enable them to be inserted into correspondingly threaded aper turesin the head or side-wall of a steam boiler 9, with which the device isto be connected. The casings 5 and 6 are connected by means of sidepieces 10, and they are separated from each other by spacing members 11,the ends of which are fitted in grooves 12, in proximate faces of thecasings. The latter are provided with sockets 13, 13 and 13 for thereception of the ends of the gage glasses 1%, 14 and 14 of which anydesired number may be used; in the drawings hereto annexed, three suchglasses have been shown.

The casings 5 and 6 are provided with vertically alined bores 15 formingseats for the regulating valve V, the valve seats 15 communicating atone side with the bores 16 of the tubular extensions 7, of the easingsand (3; said casings are provided with divergent channels 17, 17 and 17connecting the opposite sides of the valve seats 15 with the sockets 13,13 and 13, respectively.

The sockets formed in the upper casing 5, for the reception of the upperends of the gage glasses extend completely through said casing, theupper ends of the sockets being closed by means of screw-threzuled plugs18. The lower casing 6 has a downward extension 19, which is providedwith a transverse bore 20 constituting a seat for the try-cock 21; thelower side of said bore or seat communicating with a downward extendingdischarge aperture 22, while the upper side of the bore orseatcommunicates through a plurality of divergent channels 23, 23 and 23with the sockets wherein are seated the lower ends of the gage-glass.The try-cock 21, has a port or passage 2 1, which is so constructed thatany one of the gage glasses may be placed in communication with thedischarge aperture 22, or communication between said discharge apertureand each of the gage-glasses may be completely out off. The regulatingvalve V has two heads 25 engaging the seats 15 in the casings 5 and 6,respectively; said heads being provided with ports or passages wherebythe tubular extensions of said casings leading to the boiler may besimultaneously placed in communication with the upper and lower ends ofany one of the gage glasses, or communication may be cut off whendesired; for convenience in construction, the stem 26 of the regulatingvalve has been shown as being formed'in two pieces, assembled by ascrew" or fastenin member 27 the valvestem is 23 7 I provided with ahandle 28 whereby it may handle 28 is preferably provided adjacent toits outer end with an aperture 31, for the convenient attachment ofanoperating m'ember, such as a cord, chain or the like, which may beguided to a slightly distant point whereit may be grasped by theoperator who will thus be enabled to manipulate the valve handle 28without danger of his hand being scalded by steam escaping, through abroken gage-glass.

From the foregoing description taken in connection with the drawingshereto anneXed, the operation and advantages of this invention will bereadily understood by those skilled in the art to which it appertains.Normally the regulating valve is adjusted to place the steam and waterspace of the boiler in communication with one of the gage-glasses, whilethe try-cock is normally positioned to cut off communication between thegage-glasses and the discharge aperture 22. In case of injury to orstoppage or breakage of the gage-glass which is temporarily in use, aslight turning of the regulating valve will deflect the flow of waterand steam into another glass, the broken or injured glass being cut offfrom communication with the boiler. This operation may beperformed'in amoments time, and without the least inconvenience or loss of time. Byproper adjustment of the try-cock the gage-glasses may be blown outwhenever desired.

This invention, as will be seen, is eX- tremely simple in constructionand operation, and by its use much annoyance and loss of time may beavoided.

Having thus described the invention, what is claimed is:

1. A gage for steam boilers, comprising a plurality of gage glasses;casings having sockets forming seats for the upper and lower ends ofsaid glasses, vertically alined bores forming valve seats, and tubularextensions connecting the valve seats with the established between theboiler and any one of the gage glasses.

2. A gage for steam boilers comprising "casings having sockets, aplurality of gageglasses seated in the sockets, side pieces connectingthe casings, and spacing members interposed between the caslngs andengaging grooves in the. proximate faces of said .caslngs.

3. A gage for steam, boilers, comprising upper and lower casings havingsockets, side pieces connecting the casings, spacing members separatingthe casings, and a plurality of gage glasses seated in the sockets ofthe ;casings;' and a regulating valve having heads seated in thecasings, said valve beiu" provided with a separable stem and means forconnecting the parts of said stem.

4. In a device of the class described, an upper and a lower casinghaving socket-s, a plurality of gage-glasses seated in said sockets,plugs forming closures for the upper ends of the sockets in the uppercasing, a downward extension upon the lower casing having a valveddischarge aperture and divergent channels connecting said aperture withthe sockets wherein the lower ends of the gage glasses are seated, saidcasings being provided with vertically alined valve seats, with tubularextensions communicating with the valve seats at one side of the latter,and with divergent channels connecting the opposite sides of the valveseats with the sockets, wherein the gage-glasses are seated; and a valvehaving heads engaging the seats in the casings and provided with portsthrough which communication may be established between the tubularextensions leading to the boiler and the divergent channels leading toany one of the gage-glasses.

In testimony whereof I atlixmy signature in presence of two witnesses.

OSCAR OTTESEN.
